levels may cause permanent hearing loss.
Individuals vary considerably in susceptibility to noise-induced hearing loss, but
nearly everyone will lose some hearing if
exposed to sufficiently intense noise for a
period of time. The U.S. Government’s Occupational Safety and Health
Administration (OSHA) has specified the permissible noise level
exposures shown in the following chart.
According to OSHA, any exposure in excess of these permissible limits
could result in some hearing loss. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons
exposed to equipment capable of producing high sound pressure levels use
hearing protectors while the equipment is in operation. Ear plugs or protectors in
the ear canals or over the ears must be worn when operating the equipment in
order to prevent a permanent hearing loss if exposure is in excess of the limits
set forth here.

INTRODUCTION
Thank you for choosing Mackie Designs’
sound reinforcement speakers.
The C300 has a Speakon® input, and the
C300i has a 1/4 inch phone jack. Apart
from this difference, all details in this
manual apply to both models.
The C300 is a portable two-way loudspeaker system, capable of extremely high
sound pressure levels, and designed to give
you the best performance of any loudspeaker
in its class and price range.
Mackie Designs’ entry into the sound
reinforcement loudspeaker market began
with the acquisition of Radio Cine Forniture
(RCF), headquartered in Reggio Emilia,
Italy. RCF has a long tradition in developing speaker technology for the high-end
pro-audio market.
The Transducers
The C300 features a 12” high-power
low-frequency woofer and a 1.75” mylar
diaphragm high-output compression driver.
The woofer incorporates technology used
in large-format touring systems and, with a
massive, precision 3-inch voice coil, is virtually indestructible.
The high-frequency compression driver
is mounted on a multi-cell aperture loaded
on a constant directivity horn, providing an
ultra-wide, controlled dispersion pattern and
precise reproduction of the critical upper
mid-range and high-frequencies. The result
is an unbelievably smooth off-axis response
that allows everyone in the audience to experience the same high-resolution audio no
matter where they are seated.
Each driver has been specifically designed
by our engineers for optimum performance
in a lightweight high-strength cabinet.
The Crossover
This unique Low Impedance Compensated Crossover (LICC) design places
inductors in series with the woofer whose
values are markedly lower than conventional designs. This reduces the amount of
energy that is typically wasted as heat and
increases the amount of energy that is
transformed into real acoustic power. It also
incorporates dynamic protection for the
compression driver from non-linear signals.
The Cabinet
The C300 cabinet was designed to be the
strongest molded composite cabinet on the
planet. This material is as strong as concrete, and rigid enough to prevent
unwanted vibrations and standing waves in
the cabinet. It has built-in fly points for
hanging, and a socket in the bottom for
mounting on a tripod stand. Although it is
an exceptional choice for installed sound
situations, its light weight and durable finish also make it ideal for portable sound
system use. The asymmetrical trapezoidal
design of the cabinet also makes it easy to
use as a floor wedge for stage monitor applications.
The C300 offers a portable, lightweight
solution for a variety of high-powered
sound reinforcement applications.
Inputs
The C300 input is a Speakon connector,
wired as follows:
Pin 1+ is Positive (+)
Pin 1– is Negative (–)
(Pins 2– and 2+ are not used)
The C300i input is 1/4” TS (tip-sleeve),
wired as follows:
The Tip is Positive (+)
The Sleeve is Negative (–)
Having these inputs on the C300i
speakers makes them an ideal choice for
use with one of our PPM-series professional powered mixers.

The C300 can be
used with a Mackie
SRS1500a Subwoofer to
create an incredibly
powerful system.
The active crossover
inside the SRS1500a
splits the full-range
stereo input signal into
two ranges. The
SRS1500a sums the left
and right low-frequency
range and plays it
through its 600 watt
amplifier and 15-inch
woofer. It sends the
stereo high-pass range
to the C300s, via an external power amplifier.
The C300 can be pole
mounted on top of the

PLACEMENT
The C300 loudspeakers are designed to
sit on the floor, a tabletop, or to fit on a
standard tripod speaker stand. They can
also be suspended by the rigging points,
shown here.
You can lay the cabinet down on its side
and use the C300 as a floor monitor. The
asymmetrical trapezoidal shape of the cabinet
provides a perfect angle for aiming up toward
performers from the front of the stage.
Warning: Do not stack
speakers in a column.
This is to avoid the
danger of toppling
speakers.
As with any loudspeakers, protect them
from moisture. If you are setting them up
outdoors, make sure they are under cover if
you expect rain.
Room Acoustics
The C300 loudspeakers are designed to
sound as neutral as possible; that is, to reproduce the input signal as accurately as
possible, monitoring the audio signal rather
than changing it.
Room acoustics play a crucial role in the
overall performance of a sound system.
However, the wide high-frequency dispersion
of the C300 helps to minimize the problems
that typically arise.

900 Dispersion
up to 18kHz
Here are some other placement tips:
• Avoid placing loudspeakers in the
corners of a room. This increases the
low frequency output and can cause the
sound to be muddy and indistinct.
• Avoid placing loudspeakers against a
wall. This, too, increases the low
frequency output, though not as much
as corner placement. However, if you do
need to reinforce the low frequencies,
this is a good way to do it.
• Avoid placing the speakers directly on a
hollow stage floor. A hollow stage can
resonate at certain frequencies, causing
peaks and dips in the frequency response of the room. It’s better to place
the loudspeakers on a sturdy table or
tripod stands.
• Position the loudspeakers so the highfrequency drivers are 2 to 4 feet above
ear level for the audience (make allowances for a standing/dancing in the
aisles audience). High frequencies are
highly directional and tend to be absorbed
much easier than lower frequencies. By
providing direct line-of-sight from the
loudspeakers to the audience, you
increase the overall brightness and
intelligibility of the sound system.
• Highly reverberant rooms, like many
gymnasiums and auditoriums, are a
nightmare for sound system intelligibility. Multiple reflections off the hard
walls, ceiling, and floor play havoc with
the sound. Depending on the situation,
you may be able to take some steps to
minimize the reflections, such as
putting carpeting on the floors, closing
draperies to cover large glass windows,
or hanging tapestries or other materials
on the walls to absorb some of the sound.
However, in most cases, these remedies
are not possible or practical. So what do
you do? Making the sound system
louder generally doesn’t work because
the reflections become louder, too. The
best approach is to provide as much
direct sound coverage to the audience as
possible. The farther away you are from
the speaker, the more prominent will be
the reflected sound.
Use more speakers strategically placed
so they are closer to the back of the
audience. If the distance between the
front and back speakers is more than
about 100 feet, you should use a delay
processor to time-align the sound.
(Since sound travels about 1 foot per
millisecond, it takes about 1/10 of a
second to travel 100 feet.)

RIGGING
The C300 cabinets are fitted with rigging
points as shown in the diagram below.
WARNING: Never attempt to suspend the
C300 loudspeakers by
their handles. If you want
to suspend them, use the
rigging points only.
Full details concerning rigging the C300s
can be found with Mackie’s Certified Rigging
Accessories, including hardware and information on safe working loads. Contact your
Mackie dealer or see our website for details.
Note: Rigging should always be performed
by professionals experienced in safe rigging
practices.

SERVICE INFO
Warranty Service
Details concerning Warranty Service are
spelled out on page 11 of this manual.
If you think your loudspeaker has a
problem, please do everything you can to
confirm it before calling for service, including reading through the following
Troubleshooting section. Doing so might
save you from being deprived of your
Mackie loudspeaker.
Of all Mackie products returned for service (which is hardly any at all), many are
coded “CND” — Could Not Duplicate,
which usually means the problem lay somewhere else in the system. These may sound
obvious to you, but here are some things
you can check:
Troubleshooting
No sound!
• Are the level controls on the mixer or
amplifier turned all the way down?
Follow the procedures in the “Quick
Start” section on page 4 to verify that all
the volume controls in the system are
properly adjusted.
• Is the signal source working (and making
union scale)? Make sure all the connecting cables are in good repair and securely
connected at both ends.
One side is way louder than the other!
• Are the level controls set the same for
both channels on the mixer and amplifier?
• Check the PAN control on the signal
source. It may be turned too far to one
side. If you’re using a stereo signal
source, it may be delivering an out-ofbalance stereo signal.
• Try swapping sides: Switch the speaker
cables coming from the amplifier at the
amplifier end. If the other side is louder
now, the problem is with the amplifier,
the mixer, or the signal source.
Poor bass performance
• Check the polarity of the connections
between the amplifier and the loudspeakers. You may have your positive
and negative connections reversed at
one end of one cable.
It hurts when I touch my arm, or my leg,
or even my head!
• You have a broken finger.
Bad sound!
• Is it loud and distorted? Follow the
procedures described in the “Quick
Start” section to verify that the levels
are set properly.
• Are all the connections are secure? It’s a
good idea to periodically clean all
electrical connections with a nonlubricating electrical contact cleaner.
• Keep practicing.
Repair
Service for the C300 is available only
from one of our authorized domestic service stations or at the factory, located in
sunny Woodinville, Washington. Service for
loudspeakers living outside the United
States can be obtained through local dealers
or distributors.
If your Mackie loudspeaker needs service, follow these instructions:
1. Review the preceding troubleshooting
suggestions. Please.
2. Call Tech Support at 1-800-258-6883,
7am to 5pm PST, to explain the problem
and request an RA (Return Authorization) number. Have your speaker’s
serial number ready. You must have an
RA number before you can obtain
service at the factory or an authorized
service center.
3. Keep this owner’s manual. We don’t
need it to repair the loudspeaker.
8
Page 9
4. Pack the loudspeaker in its original
package, including protective wrap,
endcaps and box. This is very important. Do not use styrofoam peanuts!
When you call for the RA number,
please let Tech Support know if you
need new packaging. Mackie is not
responsible for any damage that occurs
due to non-factory packaging.
5. Include a legible note stating your name,

CARE AND
MAINTENANCE
Your Mackie loudspeakers will provide
many years of reliable service if you follow
these simple guidelines:
• Avoid exposing the loudspeakers to
moisture. If they are set up outdoors, be
sure they are under cover if you expect
rain.
• Avoid exposure to extreme cold (below
freezing temperatures). If you must
operate the loudspeakers in a cold
environment, warm up the voice coils
slowly by sending a low-level signal
through them for about 15 minutes
prior to high-power operation.
• Use a damp cloth with a mild soap
solution to clean the cabinets. Avoid
getting moisture into any of the openings of the cabinet, particularly where
the drivers are located.
8. We’ll try to fix the loudspeaker within
three business days. Ask Tech Support
for the latest turnaround times when
you call for your RA number. We
normally send everything back prepaid
using UPS BLUE (Second Day Air).
However, if you rush your loudspeaker
to us by Next Day Air, we’ll treat it in
kind by shipping it back to you UPS
RED (Next Day Air). This paragraph
does not necessarily apply to nonwarranty service.

be the subject of any warranty claims before repair
or replacement is carried out. Mackie and Mackie
Authorized Service Centers may, at their option,
require proof of the original date of purchase in the
form of a dated copy of the original dealer’s invoice
or sales receipt. Final determination of warranty
coverage lies solely with Mackie Designs Inc. or its
Authorized Service Centers.
G. Mackie active monitors returned to Mackie and
deemed eligible for repair or replacement under the

within thirty days of receipt by Mackie at our
rainforest factory complex. Products returned to
Mackie that do not meet the terms of this Warranty
will be repaired and returned C.O.D. with billing
for labor, materials, return freight, and insurance.
Products repaired under warranty at Mackie's
factory will be returned freight prepaid by Mackie
to any location within the boundaries of the USA.
H. Mackie assumes no responsibility for the quality
or timeliness of repairs performed by Mackie
Authorized Service Centers.
I. This warranty is extended to the original
purchaser and to anyone who may subsequently

authorize any third party, including any dealer or

behalf of Mackie Designs or to make any warranty
for Mackie Designs.
